* Note: All regulators listed are designed for air service and have a small but significant weep to the atmosphere (see brochure for details). Customers may consider adapting one of these air regulators for inert gas service provided they deploy the devices in a well ventilated space and are technically competent to analyze all the potential risks associated with the installation.

dome loaded regulators in water technology

Equilibar’s Jeff Jennings shares his expertise on dome loaded regulators in Water Technology Magazine

The May/June issue of Water Technology Magazine features a six-page article by Equilibar founder Jeff Jennings that provides an overview of dome loaded regulators. The article compares dome-loaded technology to traditional spring-loaded technology. It also explains the differences between a pressure reducing regulator and a back pressure regulator. “Over the years we’ve learned that there Read More
